In another embodiment, first finger 175 may make a first stationary finger touch on rim 125 or a first sliding finger touch on rim 125. When a touch sensing circuit 165 disposed with rim 125 senses a first touch by first finger 175, touch sensing circuit 130 may send a signal to controller 135. Additionally, touch sensing circuit 165 may send an indication of a first touch area and/or location of first finger 175 on rim 125 to controller 135. Further, if a first finger touch is a sliding finger touch, touch sensing circuit 165 may send an indication of a first sliding finger direction (e.g. clockwise or counter-clockwise) to controller 135. In one embodiment, second finger 180 may make a second stationary finger touch on rim 125 or a second sliding finger touch on rim 125. When a touch sensing circuit 165 senses a second touch by second finger 180 on rim 125, touch sensing circuit 130 may signal controller 135. Additionally, touch sensing circuit 165 may send an indication of a touch area and/or location of second finger 180 on rim 125 to controller 135. Further, if a second finger touch is a sliding finger touch on rim 125, touch sensing circuit 130 may send an indication of a second sliding finger direction to controller 135. Sliding finger touches along rim 125 of electronic device 105 may be clockwise or counter-clockwise.

Figure 2 is a flow diagram illustrating an example process 200 for sensing one or more finger touches 100 and providing an indication to a user of wearable band 100. Example process 200 may be performed, for example, using a wearable band 100 coupled with an electronic device 105 as shown in Figure IA or Figure IB. The sensed using touch sensing circuit 130 disposed with wearable band 100. At 210, a second finger touch may be sensed using touch sensing circuit 130 disposed with wearable band 100. Finger touches in 205 and 210 may be stationary finger touches or sliding finger touches. For example, a stationary finger touch or a first sliding finger touch may be sensed on top portion 150 or bottom portion 145 of wearable band. Finger touches may be sensed in any area or location on wearable band 100. Sliding finger touches may be made in any direction and may begin and end at any point on wearable band 100.

At 215, a first finger touch may be sensed using touch sensing circuit 165 disposed on rim 125. At 220, a second finger touch may also be sensed using touch sensing circuit 165. Finger touches at 215 and at 220 may be stationary finger touches or sliding finger touches. Stationary or sliding finger touches may be sensed in any area or location on rim 125 of electronic device 105. Sliding finger touches may be made either in clockwise or counter-clockwise directions on rim 125. Sliding finger touches may begin and end at any point on rim 125.

Additionally, a first finger touch may be a stationary finger touch on wearable band 100 and a second finger touch may be a sliding finger touch on wearable band 100. Also, a first finger touch may be a stationary finger touch on rim 125 and a second finger touch may be a sliding finger touch on rim 125.

At 225, signals from touch sensing circuit 130 and/or touch sensing circuit 165 may be received at electronic device 105 indicating one or more touches on wearable band 100 and/or on rim 125.. Signals from touch sensing circuit 130 and/or touch sensing circuit 165 indicating one or more touches on wearable band 100 and/or on rim 125 may be in any form and may be specific to a particular touch sensing circuit design or implementation. At 230, a function relating the one or more touches may be provided to a user of wearable band 100. For example, controller 135 disposed with electronic device 105 may interpret signals from touch sensing circuit 130 and/or touch sensing circuit 165. Controller 135 may be configured to determine whether a touch is a stationary or sliding touch. Configuration of controller 135 may be specific to a particular design or implementation of touch sensing circuit 130 and/or touch sensing circuit 165 utilized. Controller may be configured to distinguish between signals originating from touch sensing circuit 130 and touch sensing circuit 165. If a stationary touch is received, for example, controller 135 may determine a location and/or an area of the touch on wearable band 100 and/or on rim 125 based on signals received from one or more touch sensing circuits. In one embodiment, controller 135 may be configured to compare, for example, a location of a stationary touch with a predetermined location on wearable band 100 and/or rim 125. For example, if a location of a stationary touch corresponds with a predetermined location, a function may be provided to a user of wearable band 100, for example, activating a background light. In another embodiment, controller 135 may be configured to determine the direction and/or area of a sliding finger touch on wearable band 100 and/or on rim 125. If a direction and/or location of a sliding finger touch corresponds with a predetermined direction and/or location, a function may be provided to a user of wearable band 100, such as scrolling through menus on display 110 or raising or lowering volume if electronic device 105 comprises, for example, a media player.

hi another embodiment, controller 135 may be configured to receive signals from touch sensing circuit 130 or touch sensing circuit 165 corresponding with a first stationary or sliding finger touch and a second stationary or sliding finger touch on wearable band 100 and/or rim 135. For example, controller 135 may be configured to perform a function for a user of wearable band 100 when signals are received at electronic device 105 indicating a first finger touch and a second finger touch on wearable band 100. For example, one function that may be performed by controller 135 may include causing a display backlight to turn on or off. One benefit of configuring controller 135 to receive a first finger touch and a second finger touch before performing a function may be to limit or avoid receiving signals at electronic device 100 that may correspond to unintentional or erroneous finger touches.

Figure ID schematically shows a menu scrolling function related to signals received from one or more touch sensing circuits. In one example embodiment, signals relating to a first sliding finger touch and a second sliding finger touch on wearable band 100 are received at controller 135. Upon receiving signals indicating both a first sliding finger touch and a second sliding finger touch in one direction on wearable band 100, controller 135 may cause display 110 to scroll vertically in one direction at controller 135 indicating a first sliding finger touch and a second sliding finger touch both in the opposite direction on wearable band 100, controller 135 may cause display 110 to scroll vertically in the opposite direction through a two-dimensional array of screens 185. In an another example embodiment, signals relating to a first sliding finger touch and a second sliding finger touch on rim 125 are received at controller 135. Upon receiving signals indicating both the first sliding finger touch and the second sliding finger touch in a clockwise direction, for example, along rim 125, controller 135 may cause display 110 to scroll horizontally in one direction through two-dimensional array of screens 185. Similarly, when signals are received at controller 135 indicating a first sliding finger touch and a second sliding finger touch both in a counter-clockwise direction along rim 125, controller 135 may cause display 110 to scroll horizontally in the opposite direction through a two-dimensional array of screens 185.

Without in any way limiting the scope, interpretation, or application of the claims appearing below, a technical effect of one or more of the example embodiments disclosed herein may be to provide a particular function to a user of a touch sensitive wearable band such as scrolling through a list of menu items on display 110 based at least in part on one or more stationary or sliding finger touches on wearable band 100 and/or on rim 125.

If desired, the different functions discussed herein may be performed in a different order and/or concurrently with each other. Furthermore, if desired, one or more of the above-described functions may be optional or may be combined.

Although various aspects of the invention are set out in the independent claims, other aspects of the invention comprise other combinations of features from the described embodiments and/or the dependent claims with the features of the independent claims, and not solely the combinations explicitly set out in the claims.

It is also noted herein that while the above describes example embodiments of the invention, these descriptions should not be viewed in a limiting sense. Rather, there are several variations and modifications which may be made without departing from the scope of the present invention as defined in the appended claims.
